There’s a question I get at this time of year which comes up often enough for me to want to address it here. And that is, “What should I treat duckweed, or other pond weeds with as we come into late summer and fall?”
It’s a reasonable question and one that deserves an honest and reasonable answer, which is…
Nothing at all.
I suggest to all of our clients that late season duckweed or weed problems are unfortunate but mid to late summer, or fall, is not the time to treat them. Particularly as the seasons get cooler, many of these aquatic weeds will go away all on their own. So a bit of patience can save you a lot of money if you’re smart about it.
